She appeared to have suffered from a knife injury, Sgt, Matt Christensen said in a news release Friday.

Police went to the home at the request of family members who had been unable to reach Garcia. They told police that Garcia’s boyfriend told them she had left following an argument, Christensen said.

Lt. Sean Marchand said Garcia’s stepfather told police he had not seen or heard from her since Tuesday night.

On Thursday, detectives questioned her boyfriend, Arturo Salazar, who confessed that he killed Garcia during an argument Wednesday, Christensen said.

Salazar was arrested on suspicion of murder and is scheduled to be arraigned Monday in Vista Superior Court.

The couple has a 2-year-old son and 4-year-old daughter, but authorities do not know if they saw what happened to their mother. Christensen said the children are with their maternal grandmother and her husband.

On her Facebook page, Garcia, who went by her middle name, listed her dating status as in a complicated relationship — since March 23 — with someone by a different name than Salazar.

Her Facebook page also stated that she graduated from a school in Peru in 2010.
